Acetate and triacetate fibers
can be effectively dyed
using disperse dyes. The rate
of dyeing is
more rapid with the more
hydrophobic triacetate fibers than
with acetate. Under special
conditions, azoic and vat dyes
may be used
to dye these
fibers. Acetate fibers also have
affinity for selected acid
and direct dyes.
Since acetate loses
its luster above 85°C, dyeings
must be carried
out at or below
this temperature. Addition of pigments
or solventsoluble dyes to
the acetate or
triacetate spinning
"dope" prior to fiber
spinning leads to colored fibers
possessing excellent
colorfastness, although the
colors available are limited.
